It works if the patch.diff is generated with git diff > patch.diff

Hi @nicolabertazzo

I'm working on it.

When you do not specify a path to a patch file, DSpot-diff-test-selection tries to generate one but it seems that this generation is buggy.

danglotb commented 5 years ago

Hello, #795 should fix the issue.

danglotb commented 5 years ago

795 has been merged. Please reopen this issue if you have any more trouble.

I test it on 2.1.1-SNAPSHOT and it works!
